The River Stour is a natural river with few locks.

You can use a powered boat on the 4km stretch from Ballingdon bridge to Henny Street Weir only. The rest of the river is quite shallow. You can still navigate it but you will need a boat with a shallow draft such as a canoe or rowing boat. There is a speed limit of 4mph on the whole river.

Visit the Inland Waterways Association website to see the Fens Waterways map and about the Waterways Link project.
